Hello,

  It's me again!

I've made it finally! Intel working here with nvidia card turned off 
(how can I check that it's actually turned off).

I will make a blog post in Spanish with all the changes but here there 
is kind of a summary:

  1) UEFIBooting refers to: i915.lvds_channels=2 but nowadays you have 
to use: i915.lvds_channel=2  . So no channels but channel.

  2) Applied mbp changes to ubuntu-kernel to debian-kernel (excepting 
the part where you create a new flavour).
  3) i915 not built as a module but as kernel builtin.

  4) Now I am rebuilding the kernel with some tricks for the fan and so 
that I can use backlight.

This other page (which has helped me a bit) seems to use an older patch 
for the lvds_channels stuff (note that here it is channels not channel 
;) ): http://dentifrice.poivron.org/laptops/macbookpro8,2/

The way I've done all of this I think I would be able to compile the 
bumblebee drive and try to switch and so on... but that will be in 
another spare weekend... I don't know when.

Thank you for your initial help and thank you for being so patience (I 
think that's my fourth email as a reply).

Whenever the fans and backlight work, I'll document it in Spanish and I 
will for sure, update this conversation with a link to the blog post.
